Emmetropia

Emmetropia is the medical term for normal vision, meaning your eyes focus light correctly onto the retina, allowing you to see clearly at all distances without needing glasses or contact lenses. In an emmetropic eye, the optical systems—cornea and lens—work together to produce a sharp image directly on the retina. This balanced focusing capability means that the eye's length and focusing power are aligned properly. Essentially, emmetropia represents the natural, healthy state of the eye’s ability to see clearly without corrective devices.
